Waveform data can\nbe used to produce a visual rendering of the audio, similar in appearance to\naudio editing applications.\n\n![Example Waveform](/doc/example.png \"Example Waveform\")\n\nWaveform data files are saved in either binary format (.dat) or JSON (.json).\nGiven an input waveform data file, **audiowaveform** can also render the audio\nwaveform as a PNG image at a given time offset and zoom level.\n\nThe waveform data is produced from an input audio signal by first combining the\ninput channels to produce a mono signal. The next stage is to compute the\nminimum and maximum sample values over groups of *N* input samples (where *N* is\ncontrolled by the `--zoom` command-line option), such that each *N* input\nsamples produces one pair of minimum and maximum points in the output.\n\n# Contents\n\n- [Installation](#installation)\n- [Building from source](#building-from-source)\n- [Usage](#usage)\n- [Data Formats](#data-formats)\n- [Credits](#credits)\n- [License](#license)\n- [Contributing](#contributing)\n- [Authors](#authors)\n- [Copyright](#copyright)\n\n## Installation\n\n### Ubuntu\n\nBinary packages are available on Ubuntu Launchpad [here](https://launchpad.net/~chris-needham/+archive/ubuntu/ppa).\n\n    sudo add-apt-repository ppa:chris-needham/ppa\n    sudo apt-get update\n    sudo apt-get install audiowaveform\n\n### Debian\n\nBinary packages for amd64 and arm64 architectures are available on the [Releases](https://github.com/bbc/audiowaveform/releases) page.\n\nDownload the correct package file for your Debian version, following the examples below.\n\n| Filename                           | Debian version       |\n| ---------------------------------- | -------------------- |\n| audiowaveform-1.8.1-1-12.amd64.deb | Debian 12 (bookworm) |\n| audiowaveform-1.8.1-1-11.amd64.deb | Debian 11 (bullseye) |\n| audiowaveform-1.8.1-1-10.amd64.deb | Debian 10 (buster)   |\n\nUse these commands to install the package and its dependencies.\nReplace the version number with the latest release version.\n\n    sudo apt-get update\n    sudo dpkg -i audiowaveform-1.8.1-1-12.amd64.deb\n    sudo apt-get -f install -y\n\n### RHEL, CentOS, AlmaLinux etc\n\nBinary packages are available on the [Releases](https://github.com/bbc/audiowaveform/releases) page.\n\nDownload the correct RPM for your CentOS version and use these commands to install the RPM package,\ntogether with all required dependencies.

This is not available in\nAlpine so you must compile it yourself.\n\n    apk add autoconf automake libtool gettext\n    wget https://github.com/xiph/flac/archive/1.3.3.tar.gz\n    tar xzf 1.3.3.tar.gz\n    cd flac-1.3.3\n    ./autogen.sh\n    ./configure --enable-shared=no\n    make\n    make install\n\n#### Arch\n\n    sudo pacman -S base-devel boost-libs gd \\\n      libid3tag libmad libsndfile boost cmake git\n\n#### SUSE\n\n    zypper install git cmake gcc-c++ libmad-devel \\\n      libid3tag-devel libsndfile-devel gd-devel \\\n      libboost_filesystem1_67_0-devel \\\n      libboost_program_options1_67_0-devel \\\n      libboost_regex1_67_0-devel\n\nNote: replace 1_67_0 with the boost version actually available.\n\n#### Mac OSX\n\nInstall [XCode](https://developer.apple.com/xcode/) and\n[Homebrew](http://mxcl.github.io/homebrew/), then:\n\n    brew install cmake libmad libid3tag libsndfile gd\n    brew install boost --with-c++11\n\n### Obtain the source code\n\n    git clone git@github.com:bbc/audiowaveform.git\n    cd audiowaveform\n\n### Install Google Test test framework\n\n**audiowaveform** uses [Google Test](https://github.com/google/googletest)\nfor unit testing.\nFollowing [this advice](https://github.com/google/googletest/blob/master/googletest/README.md#incorporating-into-an-existing-cmake-project)\nin the Google Test FAQ, download the source and unzip:\n\n    wget https://github.com/google/googletest/archive/release-1.12.1.tar.gz\n    tar xzf release-1.12.1.tar.gz\n    ln -s googletest-release-1.12.1 googletest\n\n### Build\n\n    mkdir build\n    cd build\n    cmake ..\n    make\n\nThe default build type is Release. To build in Debug mode add\n`-D CMAKE_BUILD_TYPE=Debug` to the `cmake` command above:\n\n    cmake -D CMAKE_BUILD_TYPE=Debug ..\n\nIf you don't want to compile the unit tests add `-D ENABLE_TESTS=0`:\n\n    cmake -D ENABLE_TESTS=0 ..\n\nTo statically link the library dependencies add `-D BUILD_STATIC=1`, for example:\n\n    cmake -D BUILD_STATIC=1 ..\n\nTo compile with clang instead of g++:\n\n    cmake -D CMAKE_C_COMPILER=/usr/local/bin/clang -D CMAKE_CXX_COMPILER=/usr/local/bin/clang++ ..\n\n### Test\n\n    make test\n\nTo see detailed test output:\n\n    ./audiowaveform_tests\n\n### Package\n\nUse the following command on Debian-based systems to build a Debian package:\n\n    cpack -G DEB\n\nor this command on Red Hat-based systems to build an RPM package:\n\n    cpack -G RPM\n\nThe packages can be locally installed (e.g., `rpm -ivh *.rpm`,\n`dpkg -i *.deb`) or installed on another system, as long as the runtime\ndependencies of the package are present (`libmad`, `libsndfile`, `libid3tag`,\n`gd` and `boost`).\n\n### Install\n\n    sudo make install\n\nBy default this installs the `audiowaveform` program in `/usr/local/bin`, and\nman pages in `/usr/local/share/man`. To change these locations, add a `-D\nCMAKE_INSTALL_PREFIX=...` option when invoking `cmake` above.\n\n### Run\n\n    audiowaveform --help\n\n## Usage\n\n### Command line options\n\n**audiowaveform** accepts the following command-line options:\n\n#### `--help`\n\nShow help message.\n\n#### `--version`, `-v`\n\nShow version information.\n\n#### `--quiet`, `-q`\n\nDisable status messages.\n\n#### `--input-filename`, `-i \u003cfilename\u003e`\n\nInput filename, which should be a MP3, WAV, FLAC, Ogg Vorbis, or Opus audio file, or a\nbinary or JSON format waveform data file. By default, audiowaveform uses the file\nextension to decide how to read the input file (either .mp3, .wav, .flac, .ogg,\n.oga, .opus, .raw, .dat, or .json as appropriate), but this can be overridden by the\n`--input-format` option. If the `--input-filename` option is `-` or\nis omitted, audiowaveform reads from standard input, and the\n`--input-format` option must be used to specify the data format.\n\nNote that Opus support requires libsndfile 1.0.29 or later, so may not be\navailable on all systems.\n\n#### `--output-filename`, `-o \u003cfilename\u003e`\n\nOutput filename, which may be either a WAV audio file, a binary or JSON format\nwaveform data file, or a PNG image file. By default, audiowaveform\nuses the file extension to decide the kind of output to generate\n(either .wav, .dat, .json, or .png, as appropriate), but this can be overridden\nby the `--output-format` option. If the `--output-filename` option is\n`-` or is omitted, audiowaveform writes to standard output, and the\n`--output-format` option must be used to specify the data format.\n\n#### `--input-format \u003cformat\u003e`\n\nInput data format, either `wav`, `mp3`, `flac`, `ogg`, `opus`, `.raw`, `dat`, or\n`json`. This option must be used when reading from standard input. It may also be\nused to set the input file format, instead of it being determined from the file\nextension from the `--input-filename` option.\n\n#### `--output-format \u003cformat\u003e`\n\nOutput data format, either `wav`, `dat`, `json`, or `png`. This\noption must be used when writing to standard output. It may also be used to set\nthe output file format, instead of it being determined from the file extension\nfrom the `--output-filename` option.\n\n#### `--zoom`, `-z \u003czoom\u003e` (default: 256)\n\nWhen creating a waveform data file or image, specifies the number of input\nsamples to use to generate each output waveform data point.\nNote: this option cannot be used if either the `--pixels-per-second` or\n`--end` option is specified. When creating a PNG image file, a value of\n`auto` scales the waveform automatically to fit the image width.\n\n#### `--pixels-per-second \u003czoom\u003e` (default: 100)\n\nWhen creating a waveform data file or image, specifies the number of output\nwaveform data points to generate for each second of audio input.\nNote: this option cannot be used if either the `--zoom` or `--end`\noption is specified.\n\n#### `--bits`, `-b \u003cbits\u003e` (default: 16)\n\nWhen creating a waveform data file, specifies the number of data bits to use\nfor output waveform data points. Valid values are either 8 or 16.\n\n#### `--split-channels`\n\nOutput files are multi-channel, not combined into a single waveform.\n\n#### `--start`, `-s \u003cstart\u003e` (default: 0)\n\nWhen creating a waveform image, specifies the start time, in seconds.\n\n#### `--end`, `-e \u003cend\u003e` (default: 0)\n\nWhen creating a waveform image, specifies the end time, in seconds.\nNote: this option cannot be used if the `--zoom` option is specified.\n\n#### `--width`, `-w \u003cwidth\u003e` (default: 800)\n\nWhen creating a waveform image, specifies the image width.\n\n#### `--height`, `-h \u003cheight\u003e` (default: 250)\n\nWhen creating a waveform image, specifies the image height.\n\n#### `--colors`, `-c \u003ccolors\u003e` (default: `audacity`)\n\nWhen creating a waveform image, specifies the color scheme to use. Valid values\nare either `audacity`, which generates a blue waveform on a grey background,\nsimilar to Audacity, or `audition`, which generates a green waveform on a\ndark background, similar to Adobe Audition.\n\n#### `--border-color \u003crrggbb[aa]\u003e`\n\nWhen creating a waveform image, specifies the border color. If not given,\nthe default color used is controlled by the `--colors` option.\n\nThe color value should include two hexadecimal digits for each of red, green,\nand blue (00 to FF), and optional alpha transparency (00 to FF).\n\n#### `--background-color \u003crrggbb[aa]\u003e`\n\nWhen creating a waveform image, specifies the background color. If not given,\nthe default color used is controlled by the `--colors` option.\n\n#### `--waveform-color \u003crrggbb[aa]\u003e[, \u003crrggbb[aa]\u003e, ...]`\n\nWhen creating a waveform image, specifies the waveform color. If not given,\nthe default color used is controlled by the `--colors` option. This option\naccepts multiple comma-separated color values, which are used with the\n`--split-channels` option to produce a waveform image with multiple channels.\n\n#### `--axis-label-color \u003crrggbb[aa]\u003e`\n\nWhen creating a waveform image, specifies the axis labels color. If not given,\nthe default color used is controlled by the `--colors` option.\n\n#### `--with-axis-labels`, `--no-axis-labels` (default: `--with-axis-labels`)\n\nWhen creating a waveform image, specifies whether to render axis labels and\nimage border.\n\n#### `--amplitude-scale \u003cscale\u003e` (default: 1)\n\nWhen creating a waveform image or waveform data file, specifies an amplitude\nscaling (or vertical zoom) to apply to the waveform. Must be either a number\nor `auto`, which scales the waveform to the maximum height.\n\n#### `--waveform-style \u003cstyle\u003e` (default: `normal`)\n\nWhen creating a waveform image, specifies how waveform is drawn. Valid values\nare either `normal`, which draws a normal waveform, or `bars`, which\ndraws the waveform as vertical bars.\n\n#### `--bar-width \u003cwidth\u003e` (default: 8)\n\nWhen creating a waveform image with the `--waveform-style bars` option,\nspecifies the width of each bar, in pixels.\n\n#### `--bar-gap \u003cwidth\u003e` (default: 4)\n\nWhen creating a waveform image with the `--waveform-style bars` option,\nspecifies the separation between each bar, in pixels.\n\n#### `--bar-style \u003cstyle\u003e` (default: `square`)\n\nWhen creating a waveform image with the `--waveform-style bars` option,\nspecifies how each bar is drawn. Valid values are either `square`,\nwhich draws the waveform bars with square corners, or `rounded`, which\ndraws the waveform with rounded corners.\n\n#### `--compression \u003clevel\u003e` (default: -1)\n\nWhen creating a waveform image, specifies the PNG compression level. Must be\neither -1 (default compression) or between 0 (fastest) and 9 (best compression).\n\n#### `--raw-samplerate`\n\nWhen using raw input audio format, this must be set to the appropriate sample\nrate, in Hz.\n\n#### `--raw-channels`\n\nWhen using raw input audio format, this must be set to the appropriate number of\nchannels.\n\n#### `--raw-format`\n\nWhen using raw input audio format, this must be set to the appropriate sample format.\nValid options are `s8`, `u8`, `s16le`, `s16be`, `s24le`, `s24be`, `s32le`, `s32be`,\n`f32le`, `f32be`, `f64le` and `f64be`.\n\n### Examples\n\nIn general, you should use **audiowaveform** to create waveform data files\n(.dat) from input MP3 or WAV audio files, then create waveform images from the\nwaveform data files.\n\nFor example, to create a waveform data file from an MP3 file, at 256 samples\nper point with 8-bit resolution:\n\n    audiowaveform -i test.mp3 -o test.dat -z 256 -b 8\n\nThen, to create a PNG image of a waveform, either specify the zoom level, in\nsamples per pixel. Note that it is not possible to set a zoom level less than\nthat used to create the original waveform data file.\n\n    audiowaveform -i test.dat -o test.png -z 512\n\nThe following command creates a 1000x200 pixel PNG image from a waveform data\nfile, at 50 pixels per second, starting at 5.0 seconds from the start of the\naudio:\n\n    audiowaveform -i test.dat -o test.png --pixels-per-second 50 -s 5.0 -w 1000 -h 200\n\nThis command creates a 1000x200 pixel PNG image from a waveform data file,\nshowing the region from 45.0 seconds to 60.0 seconds from the start of the\naudio:\n\n    audiowaveform -i test.dat -o test.png -s 45.0 -e 60.0 -w 1000 -h 200\n\nThe `--waveform-style` option allows you to produce waveform images drawn\nas vertical bars. The `--bar-width`, `--bar-gap`, and `--bar-style` options\ncustomize the immage:\n\n    audiowaveform -i test.mp3 -o test.png -w 1000 -h 200 -z auto \\\n      --waveform-style bars --bar-width 10 --bar-gap 2 --bar-style rounded\n\nYou can use the `--split-channels` option to create a waveform data file\ncontaining multiple channels, rather than combining all channels into a single\nwaveform:\n\n    audiowaveform -i test.mp3 -o test.dat -z 256 -b 8 --split-channels\n\nIt is also possible to create PNG images directly from either MP3 or WAV\nfiles, although if you want to render multiple images from the same audio\nfile, it's generally preferable to first create a waveform data (.dat) file,\nand create the images from that, as decoding long MP3 files can take\nsignificant time.\n\nThe following command creates a 1000x200 PNG image directly from a WAV file,\nat 300 samples per pixel, starting at 60.0 seconds from the start of the\naudio:\n\n    audiowaveform -i test.wav -o test.png -z 300 -s 60.0 -w 1000 -h 200\n\nIf you are using audiowaveform to generate waveform data for use in a web\napplication, e.g, using [Peaks.js](https://github.com/bbc/peaks.js), you can\nchoose whether to use binary or JSON format waveform data.\n\nThe following command generates waveform data in JSON format:\n\n    audiowaveform -i test.flac -o test.json -z 256 -b 8\n\nThe following command converts a waveform data file (.dat) to JSON format:\n\n    audiowaveform -i test.dat -o test.json\n\nIn addition, **audiowaveform** can also be used to convert MP3 to WAV format\naudio:\n\n    audiowaveform -i test.mp3 -o test.wav\n\nYou can use the `--input-format` and `--output-format` options to read from\nstandard input and write to standard output. For example, the following command\ngenerates a waveform data file by converting a video file using ffmpeg:\n\n    ffmpeg -i test.mp4 -f wav - | audiowaveform --input-format wav --output-format dat -b 8 \u003e test.dat\n\nNote: Piping audio into **audiowaveform** is currently only supported for MP3\nWAV format as well as raw audio, but not FLAC nor Ogg Vorbis.\n\n## Data Formats\n\nYou can find details of the waveform data file formats produced by audiowaveform\n[here](doc/DataFormat.md).\n\n## Credits\n\nThis program contains code from the following open-source projects, used under\nthe terms of these projects' respective licenses:\n\n* [Audacity](https://sourceforge.net/projects/audacity/)\n* [madlld](http://www.bsd-dk.dk/~elrond/audio/madlld/)\n* [pdjson](https://github.com/skeeto/pdjson)\n\n## License\n\nSee COPYING for details.\n\n## Contributing\n\nIf you'd like to contribute to audiowaveform, please take a look at our\n[contributor guidelines](CONTRIBUTING.md).\n\n## Authors\n\nThis software was written by [Chris Needham](https://github.com/chrisn),\nchris.needham at bbc.co.uk.\n\nThank you to all our [contributors](https://github.com/bbc/audiowaveform/graphs/contributors).\n\n## Copyright\n\nCopyright 2013-2025 British Broadcasting Corporation\n","funding_links":[],"categories":["TODO scan for Android support in followings","C++","Libraries Audio"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbbc%2Faudiowaveform","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbbc%2Faudiowaveform","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbbc%2Faudiowaveform/lists"}
